Paleontologists have found fossilized multicellular marine algae, or seaweed, dating back more than 555 million years, ranking among the oldest examples of multicellular life on Earth. Honing in on ...

Over 3,000 generations of laboratory evolution, researchers watched as their model organism, 'snowflake yeast,' began to adapt as multicellular individuals. In new research, the team shows how ...

Life’s leap from single-celled to multicellular organisms marks a pivotal moment in evolutionary history. This transformation laid the foundation for the complex life forms we see today. By studying ...

The origin of animal multicellularity is one of the major evolutionary transitions in the history of life. The identification and phylogenetic classification of the closest unicellular relatives of ...

Some 400 million years ago, long before dinosaurs or even trees had evolved, an enigmatic organism towered over the landscape like a prehistoric monolith. Now, new research makes the case that the ...

In multicellular organisms, there is a potential risk that cheating mutants gain access to the germline. Development from a single-celled zygote resets relatedness among cells to its maximum value ...

In a recent study, NASA-supported researchers gained new insight into the lives of bacteria that survive by grouping together as if they were a multi-cellular organism. The organisms in the study are ...

The snowflake yeast had been shipped from William Ratcliff’s laboratory at the Georgia Institute of Technology in the U.S. Regular yeast — the same organism that makes bread fluffy — grows as a single ...
